1 Introduction
POA200 portable oxygen analyzer can capture single data points and
also can monitor data continuously, and applicabl in all occasions
when an accurate oxygen concentration measurement is required. It is
widely used in many different sectors of the economy. Such as
combustion efficiency analysis , gas blending, breathing apparatus,
compost monitoring and food storage monitoring, etc.
Standard equipment includes:
POA 200 Portable Analyzer
Stainless Steel Quick Disconnect Fittings
Power Adapter
Manual
A Shoulder Strap
Carrying Case

2
Options:
Stainless steel sleeve
FPT pipe
Printer function
Software
Warning: DO NOT turn on the "bypass/sample
gas " valve before there is low concentration oxygen flow
to the analyzer. In other words: Never expose the oxygen
sensor to the air, this will greatly reduce the life of the
sensor, or even damage the oxygen sensor!

Analyzer performance characteristics:
POA200 oxygen analyzer adopts a special weak acidity
electrochemical sensor. In its measuring range the sensor is linear
and therefore, measuring oxygen concentration is very stable
with a very wide measuring range: 0-10ppm and 0-10000ppm.
The resolution for the high quality LCD screen has a 320 * 240
color high-definition screen, and also shows the oxygen density,
maximum and minimum values, the total time of measurement,
the time difference, measurement process curve, the power and
the current time. Furthermore, it can also display the
measurement process curve, which will provide a clear and
reliable process analysis data for the users.
Automatic temperature compensation is corrected for the full
range, making the instruments more adaptable to harsh
environments..
A variety of measurement settings, users can choose one
appropiate to their needs.
It can switch interface in between English and Chinese according

to the users’ needs.
The analyzer is small and portable, making it comfortable to
service multiple locations on site.
